Abstract
An elevator system (1, 1′) includes a portable emergency stop switch (2, 2′), arranged to transmit a signal (4) when activated, a signal receiver (6, 6′), arranged to receive the signal (4, 4′) transmitted by the portable emergency stop switch (2, 2′); and an elevator safety actuator (8, 8′) and an elevator safety brake (10, 10′). In response to receipt of the signal (4, 4′), the signal receiver (6, 6′) is arranged to trigger the elevator safety actuator (8, 8′) to deploy the elevator safety brake (10, 10′).
Claims15
An elevator system (1, 1′) comprising:
- a portable emergency stop switch (2, 2′), arranged to transmit a signal (4) when activated;
- a signal receiver (6, 6′), arranged to receive the signal (4, 4′) transmitted by the portable emergency stop switch (2, 2′);
- and
- an elevator safety actuator (8, 8′) and an elevator safety brake (10, 10′), wherein in response to receipt of the signal (4, 4′), the signal receiver (6, 6′) is arranged to trigger the elevator safety actuator (8, 8′) to deploy the elevator safety brake (10, 10′).
An emergency signalling system, comprising:
- a portable emergency stop switch (2, 2′), arranged to transmit a signal (4, 4′) when activated;
- and
- a signal receiver (6, 6′), arranged to receive the signal (4, 4′) transmitted by the portable emergency stop switch (2, 2′), wherein in response to receipt of the signal (4, 4′), the signal receiver (6, 6′) is arranged to output a signal (4, 4′) which is suitable for triggering an elevator safety actuator (8, 8′) to deploy an elevator safety brake (10, 10′).
A method of deploying an elevator safety brake (10, 10′) by service personnel, comprising:
- activating a portable emergency stop switch (2, 2′) by the service personnel;
- transmitting a signal (4, 4′), by the portable emergency stop switch (2, 2′), in response to activation of the portable emergency stop switch (2, 2′);
- receiving the signal (4, 4′) with a signal receiver (6, 6′);
- and
- triggering of an elevator safety actuator (8, 8′) to deploy the elevator safety brake (10, 10′), in response to the receipt of the signal (4, 4′).
